Patient's question:
On July 28, 2010, the symptoms appeared, including red spots, abdominal pain, and joint swelling pain. Gaozhou People's HospitalDoctor's answer:
A child aged three years has developed red spots, abdominal pain, and joint pain, and has been diagnosed with Henoch-Sch?nlein purpura. Henoch-Sch?nlein purpura, also known as Henoch-Sch?nlein syndrome, is a systemic vasculitis characterized primarily by small vessel inflammation. It most commonly affects children aged 2-8, with boys being more affected than girls. Clinical manifestations vary, but it typically presents acutely, with main symptoms including skin purpura, gastrointestinal and joint symptoms, as well as kidney involvement. In 30-60% of cases, clinical signs of kidney damage occur, usually within the first month, though it can occur later as well. Symptoms range in severity, with most,, accompanied by elevated blood pressure and edema, known as purpura nephritis. However, most cases fully recover, while a few may progress to chronic nephritis. Occasionally, intracranial bleeding or nosebleeds may also occur. The prognosis for this condition is generally favorable, with the course typically lasting 1-2 weeks to 1-2 months, though it can be longer in some cases. Kidney involvement often persists for several months or even years, with 1% developing persistent kidney disease. This is a common case and can be treated in most hospitals.
